2. Description of the Related Art Conventionally, when a house, a store, or the like is constructed on a site with a narrow frontage, an opening at a portion facing the road is provided with a siding wall at a portion facing the road to increase rigidity of the building. It was necessary to provide. However, when a garage is to be built on a small site, the sleeve wall becomes an obstacle, and it may be difficult to provide the wall. For example, as shown in FIG. 4, there are cases where an entrance and a garage are provided facing the road so that a sleeve wall having a width of several tens of cm cannot be taken. As described above, when there is no wall on one side of the building, the structure is extremely vulnerable to rolling in the event of an earthquake. In such a case, it is necessary to have a rigid frame structure in order to support both ends of the beam with columns.

FIG. 5 shows an example of a joint structure of columns and beams for realizing a ramen structure in a conventional wooden building. This is because a gusset plate 2 made of an iron plate is embedded in advance so as to protrude from a side surface of a pillar 1 made of an integrated material, and this gusset plate 2 is inserted into the slit of the beam 3 having a slit formed therein. A drift pin 4 is driven in from the side to connect the column 1 and the beam 3. The gusset plate 2 and the drift pin driving portion of the beam 3 are provided with holes in advance.

[0004]

In the above-mentioned conventional joint structure between a column and a beam, there is a problem that the column 1 must be arranged with its width direction facing the road, so that it cannot be applied to a narrow plan. Further, it is difficult to completely match the positions of the holes drilled in the gusset plate 2 and the holes drilled in the beam 3, and in the field work, a portion where the draft pin cannot be driven occurs, resulting in poor construction accuracy. there were.

[0005] In view of the above-mentioned conventional problems, the present invention provides a joint structure between a wall column and a floor beam using a single-layer laminated material that is advantageous for a narrow plan, has good strength, and has no problem in construction accuracy. It is intended to be realized.

[0006]

According to the first aspect of the present invention, a single-plate laminated material for connecting a wall pillar 20 made of a single-plate laminated material and a floor beam 21 by using a coupling metal fitting 24 is used. In a joint structure of a wall column and a floor beam, the joint fitting 24 has a long nut 26 having a long length on one surface of a substrate 25 cut out in a rectangular shape from a punched metal having a large number of holes formed in a metal plate. A plurality of metal fittings 24 are provided on the upper and lower portions of the floor beam 21 so that the center line of the long nut 26 is
Each of the wall columns 20 is fixed to the wall column 20 with a wood screw so as to be perpendicular to the connecting surface of the connecting bracket 24 fixed to the floor beam 21 at a position corresponding to the long nut 26.

[0007] By adopting this configuration, there can be obtained a joint structure of a wall column and a floor beam using a single-layer laminated material which has no problem in construction accuracy, is advantageous for a narrow plan, and has good strength.

[0008] Further, a second aspect of the present invention is characterized in that the floor beam 21 is formed by connecting floor panels 23 and 23 'made of a single-layer laminated material on the upper and lower sides of a plurality of webs 22, respectively. By adopting this configuration, the web is connected to the floor panel in advance, so that the construction of the floor panel is simplified.

[0009] Further, the present invention is characterized in that the floor beam 21 is a plurality of webs 22. By adopting this configuration, since only the web is used as the floor beam, it is necessary to retrofit the floor panel, but the transportation efficiency is improved.

A fourth aspect of the present invention is characterized in that the wall column 20 is provided with a vertical load receiving member 30 for supporting the floor beam 21. By adopting this configuration, the receiving material can support the floor beam supplementarily, and the receiving material can support the floor beam when the wall column and the floor beam are joined, so that the nut of the bracket and the bolt hole of the wall column can be used. Alignment is easy, and assembly can be performed reliably.

FIG. 1 is a view showing an embodiment of the present invention, wherein (a) is an exploded perspective view, and (b) is an enlarged perspective view of a fitting. The joint structure of the wall columns and floor beams of the present embodiment is as follows:
As shown in the figure, the wall column 20 is made of a single-layer laminated material, and its width W is formed sufficiently wide (for example, 910 mm) in comparison with the thickness t (for example, 140 mm).

A plurality of webs 22 are arranged side by side at intervals on the floor beam 21, and floor panels 23, 2
3 'is joined. The web 22 is made of a laminated veneer, a laminated wood, or a sawn timber.
A single-layer laminated material is used for 23 '. And web 22
And the floor panels 23 and 23 'are connected by using an adhesive or an adhesive and a wood screw.

The floor panels 23 and 23 'of the floor beam 21 are provided with a plurality of connecting metal fittings 2 of the same structure at the connecting portion to the wall column 20.
4 are attached. This connection fitting 24 is shown in FIG.
As shown in FIG. 1, a long nut 26 longer than a normal nut is welded and fixed to one surface of a substrate 25 cut out in a rectangular shape from a punched metal having a large number of holes formed in a metal plate. Then, as shown in FIG. 1 (a), the fitting 24 is fixed to the floor panels 23, 23 'formed with a clearance for inserting a nut by using wood screws. The reason for lengthening the nut 26 is to obtain welding strength, and the screw length is not so required. Further, it is preferable to use a stainless steel which does not easily rust for the above-mentioned patching metal and wood screws.

The wall column 20 has the floor panel 23,
A through-hole 27 is formed at a position corresponding to the fitting 24 fixed to 23 '. The wall post 20 thus formed
The bolt 28 is inserted into the through hole 27 of the wall column 20 and screwed into the nut 26 of the joint 24 of the floor beam to fasten the floor beam 21 to the floor beam 21. In addition, it is preferable to disperse the pressure applied to the wall post 20 by using a washer 29 for the bolt 28. It is also preferable to provide a vertical load receiving member 30 in order to temporarily support the floor beam 21 when connecting the both. It should be noted that this vertical load receiving member 30 can support the load of the floor beam after assembly.

FIG. 2 shows an example of a building using the embodiment constructed as described above. In the figure, reference numeral 20 denotes a wall column, and reference numeral 21 denotes a floor beam.

The wall pillar 20 has its longitudinal direction arranged at right angles to the frontage, and a plurality of wall pillars 20 are arranged in the depth direction. Reference numeral 31 denotes a wall beam panel for supporting a sash (not shown).

The building thus assembled is advantageous for a narrow plan because the cross-sectional dimension in the width direction is only the thickness of the wall column 20. Since the wall column 20 is wide in the depth direction, it has not only earthquake resistance in the direction between beams but also high strength in the depth direction because it also serves as a bearing wall. The floor beam 21 can also serve as an upper floor. Since the wall columns 20 and the floor beams 21 can be factory-produced in advance, transport efficiency to the site and construction efficiency are high. Since the stress can be dispersed by a plurality of fittings in the connection between the wall pillar 20 and the floor beam 21, the substrate of the fitting can be made thin. And the like.
